採用胎模锻造来代替自由锻造,可以减少机械加工的馀量,节省加工时间,节约金属。目前,各厂在实行胎模锻造时,发生的一个比较严重、而且普遍的问题,就是锻模的使用寿命不长。有些厂在个别情观下,一个锻模只能锻制十几件活,这样不但增加了锻件成本,而且也影响了整个生产。究竟是什么原因使锻模的使用寿命达不到预期的标准,我们应当採取什么方法来提高它的使用寿命,这是目前迫切要解决的问题。提高锻模使用
The use of tire forging instead of free forging, can reduce the machining allowance, saving processing time and save the metal. At present, the plant in the implementation of tire forging, the occurrence of a more serious, and the general problem is that forging die life is not long. Some factories in a particular situation, a forging die can only forging a dozen live, not only increased the cost of forgings, but also affected the entire production. What exactly is the reason why the service life of the forging die can not reach the expected standard and what method we should take to improve its service life is an urgent problem to be solved. Improve forging use
